When multiple couples are friends on Facebook and male A shares a meme with female A, then male B, seeing said meme, shares it with female B. Female B realizes that said meme was not exclusive to couple B.
Mary thought John sent her a sweet meme, then she saw that Mike sent it to Jill an hour earlier. It was then she knew she had fallen victim to sloppy second sharing.
